Social media analytics company PeopleBrowsr has launched its social search product ReSearch.ly. The new tool is designed to help brand managers and marketers find the 1% of Twitter users that matter most to them.

ReSearch.ly, at its core, is a Twitter search engine — albeit one that offers a few heretofore unseen search features to give brands insight into micro or niche Twitter communities.

The product allows users to search tweets around specified keywords. Once a search is initiated, tweets are shown in the left-hand portion of the application and users can filter the stream to show tweets from followers or those following, segment results by gender and breakout tweets by positive or negative sentiment. Results can also be narrowed by product-defined communities or location.

On the right-hand side, ReSearch.ly provides a graphical global overview of tweets for 30-day or seven-day time spans. Here, users will find a chart showing keyword volume fluctuation over time, a sentiment line graph and a sentiment pie chart. There’s even a word cloud highlighting common words housed within the tweets being dissected. In this area, ReSearch.ly also displays media related to tweets, including Twitpics and YouTube videos.

The company calls this technology “Viral Analytics,” and aims to help users track — in real-time — how information moves through the web.

The product also provides users with the opportunity to see degrees of separation from other Twitter users; this data can be exported to CSV.

In some ways, ReSearch.ly — which has a seven-day free trial — seems rather limited for its $99 per user, per month price tag. The unfettered access to Twitter data and the myriad of filters make for an interesting browsing experience, but there doesn’t seem to be much more you can do with the information you do discover.

Product Manager Brett Horvath says that’s because ReSearch.ly isn’t an engagement platform. “It’s a social search platform where you can find out what people are saying and map those [conversations] out,” he says. Hovarth also says its target audience — brand marketers and managers — are excited to pay for the product, which he believes provides them with unprecedented Twitter research tools.

PeopleBrowsr, as you may recall, started as a consumer-facing social application for managing Twitter and Facebook streams but has since switched to focus on enterprise-level data mining, analytics and brand engagement. The ReSearch.ly product represents the sum total of the company’s refined search technologies and its access to the full Twitter firehose.
